ller Machine). This apparatus has a structure in which a passbook is sandwiched by rollers and the passbook is conveyed in a predetermined direction by rotating the rollers.

However, since the details of the transaction record of money are printed on the bookkeeping surface of the passbook, if the transfer device frequently carries the passbook, ink on the passbook bookkeeping surface adheres to the roller surface. . When the passbook is not conveyed, the ink re-adheres to the other roller opposite thereto, and consequently, when the passbook is conveyed next, the ink is transferred to the front cover (or the back cover) of the passbook. Therefore, each time the apparatus is used, the cover of the passbook gradually becomes dirty. Poor appearance of the passbook leads to a result of impairing the service for the user, which is not preferable in practical use.

[0004] In order to solve such a problem, the transfer of the ink is prevented by increasing the chance of cleaning the roller surface, but the use of the apparatus is temporarily stopped, and the service to the user is deteriorated. Is inevitable. Further, labor for maintenance is required.

[0005]

As described above, in the conventional medium transport apparatus, the ink on the passbook bookkeeping surface adheres to the roller surface for transporting the passbook, and this ink is transferred to the cover of the passbook. I will. Therefore, each time the apparatus is used, the cover of the passbook gradually becomes dirty.

The present invention has been made to solve such a conventional problem, and has as its object to provide a medium transport apparatus in which ink is not transferred to the cover of a passbook. [Configuration of the Invention]

When the passbook 1 passes between the first rollers 2a, 2b and the second rollers 7a, 7b, the first rollers 2a, 2b and the second rollers 7a, 7b are again in their concave portions. And the convex portions come into contact with each other so as to face each other. Hereinafter, the same operation is repeated when the next passbook is conveyed.

In this embodiment, by performing such an operation, only the convex portions of the first rollers 2a and 2b come into contact with the recording surface 1a of the passbook 1 when the passbook 1 is transported. After the passbook 1 has been conveyed, the first rollers 2a and 2b come into contact with the second rollers 7a and 7b. At this time, the convex portions of the first rollers 2a and 2b are connected to the second rollers 7a and 7b. , 7b, so that the projections do not come into contact with each other. That is, the ink on the book surface 1a of the passbook 1
And adheres to the concave portions of the second rollers 7a and 7b. However, even if the next passbook is conveyed, the ink of the previous passbook 1 is not transferred to the cover of this passbook. This solves the problem that the passbook has a poor appearance.

In order to position the first roller 2a, 2b and the second roller 7a, 7b such that the concave and convex portions thereof face each other, the concave and convex of the rollers 2, 7 and the gear 6, The number of teeth may be the same as 9 or one may be an integral multiple of the other. Also in this case, when fixing the rollers 2 and 7 and the gears 6 and 9 to the shafts 3 and 8 so as to match the phases of the rollers and the gears, the gears 6 and 9 are simply positioned so as to mesh with each other. Only by this, the concave portion and the convex portion can be easily made to face each other.

1 are arranged so as to face each other in a state of being separated from the end of the passbook 1.

In this embodiment having such a structure, the rollers 2 and 7 are always kept at their flat portions 10 and 1 when the passbook 1 is transported.
One is in contact with each other. Therefore, the concave portions and the convex portions of the rollers 2 and 7 do not mesh (engage), and the first rollers 2a and 2
b can be quickly pushed upward.

Also, as in the third embodiment shown in FIG.
The rollers 2 and 7 provided with the flat portions 10 and 11 may be arranged at positions where they come into complete contact with the passbook 1. In this case, the same effect as in the second embodiment can be obtained. Further, even if a high pressing force is applied when the passbook 1 is conveyed, the flat portions 10 and 11 of the rollers 2 and 7 absorb this pressing force, so that when the passbook 1 is conveyed, the passbook 1 contacts the rollers 2 and 7. Deformation due to contact with the part is prevented. As a result, it is possible to increase the holding power of the passbook 1 and to make it difficult for the passbook 1 to be deformed. The flat portion 1 as in this embodiment.

It is desirable to arrange the flat portions 10 and 11 so as to be located outside the printing area of the passbook 1. Next, a fourth embodiment of the present invention will be described with reference to FIG.

In this embodiment, a timing belt 12 having a plurality of irregularities formed on the inner periphery is used, and the timing belt 12 adjusts the phase of the irregularities between the rollers 2 and 7. The timing belt 12 is fixed to the shafts 3 and 8 and meshes with pulleys 13 and 14 having a plurality of irregularities formed on the outer periphery thereof. Further, a roller 15 is in contact with the timing belt 12, and a predetermined tension is applied to the timing belt 12.
When the passbook 1 is carried in, the rollers 15 move the first rollers 2.
It is possible to finely adjust the tension of the timing belt 12 within a range in which a and 2b are allowed to be pushed upward. Next, a fifth embodiment of the present invention will be described with reference to FIGS.

First rollers 2a and 2b in the present embodiment
Further, grooves are formed in the second rollers 7a and 7b along the circumferential direction thereof, thereby forming an uneven portion. As is clear from FIG. 7 which is a cross-sectional view taken along the line BB in FIG.
Are arranged such that the concave portion and the convex portion face each other.
The phases of the concave and convex portions are adjusted by using rollers 2 and 7 on shafts 3 and 8.
It is only necessary to accurately position both members in the axial direction when fixing them. Here, the flat portions 1 described above are applied to the rollers 2 and 7.
Although 0 and 11 are formed, they need not always be formed.

According to the present embodiment, unlike the above-described embodiments, the first rollers 2a, 2b
Moves upward, the phase relationship between the concave and convex portions of the rollers 2 and 7 does not change at all. Therefore, the reliability is extremely improved in terms of preventing ink transfer.

As another operation of the present embodiment, there is the following operation. Generally, in an ATM or the like, a printing mechanism that prints a predetermined transaction record on a passbook also serves as a printing mechanism of a bill statement. On the other hand, the passbook outlet and the bill statement outlet are generally different. That is, after printing the bill, it is necessary to move the bill to another take-out mechanism.

In this embodiment, when the medium is conveyed in a direction perpendicular to the conveying direction, the rollers 2a and 2b (or rollers 7a and 7b) are slightly moved in the axial direction to make the rollers 2 and 7 uneven. Can be configured to match (FIG. 8). This allows the rollers 2, 7
As a result, the state of pressure contact with the medium can be assured, and stable conveyance in the orthogonal direction can be performed. In particular, a remarkable effect is exhibited for a medium having a small thickness as in a bill specification. In addition, as a method of minutely moving the roller in the axial direction, there is a method of driving a shaft by a piezoelectric element or the like.

In this embodiment, a roller is used as an example of a member for pressing the passbook 1, but the passbook may be pressed and conveyed using a belt instead of the roller. In this case, the grooves may be formed in either the driving direction of the belt or the direction perpendicular to the driving direction. Further, the grooves formed in the pressure contact members such as the rollers and the belt need not be formed in a straight line, but may be formed in a spiral shape, for example.
